In The Murder of Roger Ackroyd, The Three Boars is an inn in King's Abbot. When Ralph Paton returned to the village and chose to stay there instead of Fernly Park, the reason for this became a matter of much speculation among the villages. As Paton later became a prime suspect in the murder of Roger Ackroyd, the inn, who went there and why became a matter of significance.
From hints in the text, it appears that the Three Boars is the only public house in the village. After the death of Roger Ackroyd, the Three Boars was one of the options for the venue. The text does not state where the inquest was eventually held.
